Yes that is true. I am not sure however how that would relate to JFreeChart since JFreeChart doesn't really have a lot of graphics painted. I've done applications that use Java2D which is a lot faster, but with more stuff going on. Do you have any other ideas what it could be David? I appreciate all...

Ok it seems like decreasing the charts sizes (by resizing the JFrame the charts are in) it goes significantly faster. Why is this?!

I will try the setNotify thing. Are you certain there's nothing with sorting of the lists each time a new time/value is added to TimeSeries?

edit: Also, would DynamicTimeSeries help in any way?
edit2: I tried the notify thing but it's still slow. Changing the alias doesn't help much either.

Real-time usage slowdown

I've got some problems with JFReeChart beeing really slow in real-time. I am basically using the charts for real-time purposes where I draw 7 different charts (4 xyplots as with timeaxises, and three bar or dial charts). I am guessing it's the timeseries chart that are slow? Would using DynamicTimeS...

That is a very good idea. Why didn't I think of that. Thanks! Edit: Having a hard time figuring out how to do this. Any hints? I am guessing I should edit the else to check for the size of my dataset and return true only if it "int item" equals the datasetsize-1, I'm just not sure how to do that. Go...

I figured out a way to do it myself. Going to test this way too to see what gives me the best performance. (I'm drawing dynamic/realtime charts to performance is an issue)

Thanks a ton though and I do appreciate the help.

Addint a figure/shape to the end of the XYSeries

Hey!

I am wondering if someone knows how to add a small figure/shape to the last datapoint added to a XYSeries? I just want to indicate that a certain point was the last oen added.

Thanks.

Drawing datapoints in the order they were added to the serie

Hi! I've got another delicate problem. I tried browsing the API but couldn't find the solution. What I want to do is very simple to understand. I am currently using a XYSeries and XYSeriesCollection. I am adding points one by one from a list with about 300 points. As you know, when I add a new point...

Hi again paradoxoff! I've been having a vacation so I didn't get time to test anything. I'm on it now and just wanted to report my findings. I tried changing the background color, but the same effect didn't happen. So it does indeed have to do with removing the legend. Also, a very strange thing is ...

Very thorough reply paradoxoff. You are entirely correct when you assume that I am not setting any renderer property color explicitly and I rely on defaults. I do however set other renderer properties. Just not the color property. A petty detail, but I assume you mean that StandardXYItemRenderer cal...

I've never used a SpiderWebPlot, but have you tried setting a new shape via the setLegendItemShape(java.awt.Shape) and see what it does?
